If your kids are old enough, have them help! It seriously makes things go so much more smoothly on a daily and weekly basis.
My 10 year old lays out his clothes the night before, makes sure his backpack and after-school stuff is ready, and packs his water bottle. He also gets himself up each morning and makes his own breakfast (usually toast or cereal). My 7 year old isn't quite that independent, but she helps me pick out her clothes the night before, and gets herself dressed in the morning.
We are always pressed for time during the week between work, school, and after-school activities, but having the kids manage some of their own tasks helps us stay organized and efficient.
